I am using STM32H745BIT6 MCU and I want to add support of BLE and WIFI with this MCU. So please suggest external BLE/Wifi module compatible with STM32H745xx MCU and having nice support/demo examples available.

Matter support?

Does ST plan to support Matter? Are there any code examples or application notes available (I couldn't find any). Also, specifically, will a single STM32WB55 be able to support Matter connectivity and provisioning (seems like it should).Thanks! Dan.

Resolved! How to Actively Disconnect Bluetooth Connection of Mobile Phone？

When STM32WB is used as slave device, how to actively disconnect Bluetooth connection of mobile phone?

Resolved! Is the stm32xxxx_hal_conf.h missing in stm32xxxx_hal_***.h?

Hello,I was creating a new project for STM32WL in STM32CubeMX today, and I wanted to use the "register callbacks" functionality for a timer peripheral. So I have enabled the callback feature and generated the project. When I opened it the symbols for...

How to optimize power consumption by SAI

I'm developing a battery powered application using the STM32WBMMG and working to minimize power consumption. I'm using STM32Monitor-Power and X-NUCLEO-LPM01A to supply power to our custom board and measure current. The application periodically uses ...

Using VBAT pin for monitoring battery voltage in STM32 microcontroller

I am updating a PCB design that uses STM32WB35XX series microcontroller and 3 V CR2032 coin cell battery. I want to monitor the voltage level of this battery using the VBAT pin of the microcontroller. I know that is possible as specified in the pictu...

Resolved! Is there any way to read the comparator's output voltage without connecting the output pin to the ADC?

I know the microcontroller has built-in comparators and I'm trying to use it as a transimpedance amplifier. So, I want to test the comparators but the Necleo-WB55 developer kit doesn't have built-in comparators. So, I have to test it on my custom boa...

How to change advertising structure order in BLE

I am using STM32WB55 controller for BLE. I am using it with peripheral lite example. As I can see in the advertising data, the manufacturer specific data comes first and followed by flags and UUID. How to send in order like flags -> UUID -> manufactu...

The memory size of STM32WBCG55 in STM32CubeIDE doesn't match to the datasheet.

Hi, stm.The build analyzer of the CubeIDE showed the full memory size and the usage. When I build my custom project of stm32wb55cg, the size of flash and ram did not match to the datasheet.The below image shows the result.In the datasheet, the flash ...
